◆ board_ns()

int64_t fsw::time::anonymous_namespace{BoardClockSync.cpp}::board_ns ( uint64_t unwrapped_ms )

inline

Board timeline position in ns.

All offset math is exact int64 — doubles cannot represent epoch-ns (53-bit mantissa) and the rounding error would leak into the future-clamp comparison.
